| abstract |
The present invention provides an adhesive composition that is used in an image display device or the like and is excellent in durability, removability (reworkability), and stress relaxation properties. The pressure-sensitive adhesive composition of the present invention comprises N-vinylcarboxylic acid amide (a1) and (meth) acrylic acid ester (a2) in a mass ratio of (a1) / (a2) = 1/99 to 90. In the range of / 10. Furthermore, a polymerizable monomer having a total sum of N-vinylcarboxylic acid amide (a1) and (meth) acrylic acid ester (a2) of 80% by mass or more of the total monomers contained in the composition or a partial polymer thereof (A ) And (A) 0.01 to 5 parts by mass of the crosslinking agent (C) with respect to 100 parts by mass.
